I have a iPhone 3G 16GB White, this is my first phone for roughly everything. However, their are certian times when I do not wish to move my iPhone 3G to sure places. I have a aged Motorala pre-paid GoPhone from AT&T which I paid for a integrate of months ago. If I place my iPhone 3G’s SIM Card in this phone will I be means to operate it on my family devise with my mins and total texting when I do not wanna move my iPhone with me? It would only be for about 2 to may be 10 hours a day each integrate of days. Would they take my Data devise off when I’m regulating this phone or couyld I leave it on since I only wanna operate this phone for a integrate of hours afterwards operate my iPhone again. Because of my iPhone Data Plan weould I be means to acess it’s Data facilities similar to Media Net or Mobile Web? Thanks.
